I'm confused. Who are you, nasr91, that you're responding as if you're the OP that no one was helping (for a whole 2 hours, cry me a river).
Now, OP, a little more detail would be helpful. What exactly is stuck? Is it simply that the button seems to always be pressed? A lot of times, that's because the computer's battery as swollen and is pressing on the trackpad from underneath. I'd check that first. It's also possible there's dirt or something under the trackpad or in the side, so carefully cleaning it could be helpful.
